    Download installation files deleted after downloading ISO

    I had the Windows 10 install files in $WINDOWS.~BT and $Windows.~WS totalling >5GB. A few days ago I decided to also download the Windows 10 ISO.

    I've now found that the 5GB+ installation files have been deleted.

    I'd like to have both options regarding the upgrade and so would like to re-download the installation files. How do I get them re-downloaded?

    If I click the Get Windows 10 icon the only option is Upgrade Now, not what I want - unless that will initiate a download and then give me the option of not starting the actual upgrade.

    Hope this makes sense.

  3. Installing Windows 10 without Windows Setup Temporary Files

    Hi Karthicka,

    Just to confirm, are you saying that I can't simply upgrade to Windows 10 if I have deleted by "Windows Setup temporary files"? I already have the upgrade downloaded onto my computer, I just have to install it. Are you saying that I must install from an
    ISO file instead?

    Thanks for your help.

    ETA: To clarify, I deleted my temporary setup files, reserved my copy of Windows 10, downloaded it, and have not yet installed it. I did not delete the temporary setup files after downloading Windows 10.

    I know you want to have both options, but it really is not necessary. You have the ISO file. That's more than enough.

    As to the disappearance of $Windows.~BT and WS....................
    Did you do any disk cleanup using the built-in Disk Cleanup or using Ccleaner ?
    Did you recall you selected to delete the "Previous installation file " in order to delete windows.old ?
    I know that happened to me when I used Ccleaner and selected that option under Advanced heading.

    I do use Ccleaner regularly but have nothing selected under Advanced. And the files disappeared recently, and I use Ccleaner frequently, I don't think that was the culprit.

    Ok, though I understand I don't really need the large download files as I have the ISO, can I go back to having those files, and if so how do I get them to be downloaded?

    Sorry, I have no answer for you.

    To download them again, delete the $Windows.~BT and the $Windows.~WS folders, then run Windows Update several times until you see the Get Windows 10 icon again. Click on it, there should be an option to download for installing on a different computer, rather than install now. Select this option to download the files for later use.

    Download installation files deleted after downloading ISO

    Sorry to resurrect an elderly thread.

    Two questions:

    • Clicking the Get Windows 10 icon I get the choice of upgrading now or of downloading the install files. After choosing to download, having deleted the $Windows.~BT and the $Windows.~WS folders, Windows Update runs but tells me my Windows is up to date. I can't get it to actual download the files.
    • Although I have the .ISO, as I understand it, that can only be used to do a clean install for a system that's already been upgraded to Win 10. In other words one that MS knows is legal. Else how will it know to activate?
    To be honest, I'd prefer to do the upgrade to avoid the pain of reinstalling everything.

    No, that isn't true. You can definitely use the ISO to do an upgrade.

    If you are on Windows 8 mount the ISO and click on setup.exe. If you are on Windows 7 extract the ISO to a folder on the desktop and click on setup.exe. Do not try to boot from the ISO as that is for a clean install.

    Have a look at this tutorial starting on step 7 (as you already have the ISO). Windows 10 - Upgrade Installation - Windows 10 Forums

    It checks you have a valid installation as part of the upgrade procedure and (assuming you are) will not ask you for a key.

    Excellent! Many thanks.

    I'd thought the ISO was only for clean installs - I've that already on my laptop, hadn't realised it can be used for an upgrade as well.

    Thanks you.

    You are most welcome. Good luck with it *Smile

    And the good news about the ISO is that you don't need SP1 in Windows 7 or upgrade Windows 8 to 8.1 first. The ISO can upgrade directly from Windows 7 RTM or from Windows 8.0

    Uh-oh. Now we're going to get the two or three members on here who insist that you can't. Even though many, including myself have done it.
    NavyLCDR, Jan 13, 2016
  14. My guess is the ISO download uses those same hidden folder(s). They are used as temporary storage of the files until the ISO is created. Then they likely get deleted as a cleanup after function. Wait long enough, and you may get your files downloaded again in the background by the GWX App in the notifications area.

    Not every ISO. I'm referring to the ISO you download from Microsoft Tech Bench site. This can install straight from 7 or 8. The ISO you create from Get Windows 10 utility cannot.
